Abstract

An inductor element is formed by helically winding a first conductor and a second conductor by causing both conductors to hold on the condition in parallel to each other. In this case, by causing the first conductor to intersect the second conductor at a predetermined position to replace individual positions. By virtue of this arrangement, individual length of the first and second conductors substantially equal to each other, whereby forming up such an inductor element characterized by less loss of current and higher Q values.

Claims

1. An inductor element having a plurality of conductors formed on a surface of a substrate thereof to be helically wound within a plane surface in mutually parallel relationship, which is utilized on a high-frequency path for allowing high frequency current of an identical phase to flow through said plurality of conductors;

wherein, said plurality of conductors intersect themselves at a predetermined position so that inner positions and outer positions of said plurality of conductors are replaced with each other; and

said predetermined position for allowing said plurality of conductors to intersect is selected so that individual length of said plurality of conductors are substantially equal;

whereby said plurality of conductors extend from a common first terminal to a common second terminal and have no conductors positioned between them.

2. The inductor element according to claim 1, wherein said plurality of conductors provided for said inductor element comprise a pair of conductors.

3. The inductor element according to claim 1, wherein said plurality of conductors provided for said inductor element comprise two pairs of conductors, wherein said two pairs of conductors are adjacent to each other;

said two pairs of conductors intersect themselves on a predetermined line and are helically wound;

wherein each pair of conductors intersects each other at a symmetrical position with regard to said predetermined line.

4. An integrated circuit comprises an inductor element having a plurality of conductors formed on a surface of a substrate thereof to be helically wound within a plane surface in mutually parallel relationship, which is utilized as a high-frequency path for allowing high frequency current of an identical phase to flow through said plurality of conductors;

wherein, said inductor element having said plurality of conductors intersect themselves at a predetermined position so that inner positions and outer positions of said plurality of conductors are replaced with each other;

whereby said plurality of conductors extend from a common first terminal to a common second terminal and have no conductors positioned between them.

5. The integrated circuit according to claim 4, wherein said plurality of conductors provided for said inductor element comprise a pair of conductors.

6. The integrated circuit according to claim 4, wherein said plurality of conductors provided for said inductor element comprise two pairs of conductors;

wherein said two pairs of conductors are adjacent to each other;

said two pairs of conductors intersect themselves on a predetermined line and are helically wound;

wherein each pair of conductors intersects each other at a symmetrical position with regard to said predetermined line.
